Definitions
- This invention relates generally to the field of refuse handling apparatus.
- this invention relates to refuse collection vehicles of a type having a hopper for receiving refuse and a storage body for receiving and storing refuse from the hopper.
- the present invention concerns novel features for the improved control and operation of refuse collection vehicles.
- the mechanized unit, or collection vehicle included a refuse handling body mounted upon a truck chassis. Generally, the vehicle was attended by a crew of three or more. One of the crew attended to operation of the vehicle while the others brought the householder's refuse to the vehicle.
- the vehicle included a hopper of conveniently low loading height into which the collectors emptied the containers. Means were provided for transferring the refuse from the hopper to the body.
- the body which was typically equipped with a compactor, also included unloading means for ejecting refuse at the disposal site.
- the storage bodies of most refuse collection vehicles have also grown to accommodate larger loads.
- practitioners in the field have been faced with the technological necessity of making the large storage bodies strong enough to accommodate not only the weight of the refuse but also the force exerted against the storage body as the refuse is compacted into the storage body from the hopper.
- the walls of present storage containers are quite bulky and normally either corrugated or otherwise include vertical and/or horizontal bracing elements welded to the walls to rigidify and strengthen the walls.
- corrugated walls and walls having vertical and/or horizontal braces exceedingly expensive to construct and heavy, they also diminish the general exterior appearance of the storage body and the aerodynamic quality of the refuse collection vehicle which correspondingly decreases the gas mileage of the refuse collection vehicle during normal operation increasing the cost of operating tie vehicle.
- many storage containers incorporate a gate assembly mounted with a rearward opening thereof to act as a closure for the rearward opening.
- These gate assembly apparatus are normally bulky and incorporate complex mechanical features for locking and unlocking the gate assembly with the rearward opening.
- the accessible rearward opening allows refuse collected within the storage container to be ejected from the rearward opening.
- apparatus currently exist for either tilting the storage body upwardly for allowing gravity to move the refuse from the storage body and outwardly through the rearward end for deposit, or ejecting the refuse outwardly through the rearward end.
- Another object of the present invention is the provision of an improved storage body which is light, strong and capable of transporting large loads of refuse.
- Yet another object of the present invention is to provide an improved storage body that is easy to construct.
- Still another object of the present invention is to provide an improved storage body that is inexpensive to construct.
- Yet another object of the instant invention is to provide an improved continuously operable packer assembly.

- sidewall 309 further includes an aperture 311 formed therethrough. and diametrically opposed with bore 307 and operative for receiving pin 294 therethrough, further details of which will be presently discussed.
- fixture 301 is carried within chamber 281 of housing 280 in a generally inverted orientation and desirably rests upon carriage assembly 230 with upstanding element 253 received into and through trench 308 and pin 294 extending into and through bore 307 of guide 300 . In this manner of orientation, pin 294 directly opposes upstanding element 253 as shown.
- upstanding element 253 is provided with a plurality of apertures 312 extending therethrough and disposed therealong from a point just rearward of support plate 270 to proximate rearward end 252 .

- platen 187 Upon movement of pin 294 into the extended orientation in the foregoing manner, platen 187 thus becomes fixed to carrier element 232 .
- fixture 301 captured within housing 280 between forward endwall 284 and rearward endwall 285 , actuation of linkage assembly between the retracted and extended orientations will cause platen 187 to correspondingly move coincident with the movement of carrier element 232 in response to actuation of linkage assembly 180 between the retracted and extended orientations.
- base 302 of fixture will bear against forward endwall 284 to force platen 187 to move along the forward stroke as carrier element 232 traverses along the forward stroke as defined by stroke path 190 (FIG.
- pin 294 operative as an engagement element, may be engaged with aperture 312 , operative as a complemental engagement element, located just rearward of support plate 270 . Accordingly, with platen 187 mounted with carrier element 232 in this fashion, movement of linkage assembly 180 to the retracted orientation will define a fully retracted orientation of platen 187 within hopper 61 . In this fully retracted orientation of platen 187 , refuse may properly be collected and placed within hopper 61 rearwardly of platen 187 adjacent rearward surface 222 of panel 221 .

- linkage assembly 180 may be actuated from the retracted orientation along the rearward stroke to the extended orientation for correspondingly moving platen 187 from the fully retracted position to an extended position for transferring refuse from hopper 61 through upstream opening 80 of storage body 62 .
- cylinder assembly 290 may be actuated for retracting operating rod 293 inwardly as indicated by the arrowed line w in FIG. 36 to move pin 294 along the same directional traverse to disengage pin 294 from the selected aperture 312 for consequently disengaging engagement assembly 282 from carriage element 232 thereby disengaging platen 187 from carrier element 232 .
- linkage assembly 180 may be actuated from the extended orientation to the retracted orientation pulling carrier element 232 along carriage 231 toward upstream end 82 of hopper 61 , platen 187 remaining in a stationary position and carrier element 232 sliding forwardly within tunnel 283 and notch 286 .
- cylinder assembly 290 may be actuated for moving operating rod 293 outwardly in the direction indicated by the arrowed line V in FIG.
- linkage assembly 180 may be actuated along its rearward stroke for facilitating the movement of platen 187 rearward throughout the rearward stroke of linkage assembly 180 into and through storage body 62 a distance equal to path stroke 190 .
- This process may be repeated until platen 187 is finally positioned adjacent downstream opening 81 of storage body 62 resulting in the incremental and downstream traverse of platen 187 from upstream end 82 of hopper 61 to downstream opening 81 of storage body 62 for facilitating the transfer and ejection of refuse outwardly through downstream opening 81 .
- closure element 91 of gate assembly 90 will need to be in the open position for facilitating the ejection of refuse outwardly from downstream opening 81 .
- rearward end 252 of carrier element 232 may be provided with a stop 313 carried by upstanding element 253 as shown in FIG. 31 and constructed of a size sufficient not to admit past notch 287 of rearward endwall 285 of housing 280 .
- stop 313 is comprised of a nut 314 mounted with upstanding element 253 at rearward end 252 of carrier element 232 and a bolt 315 threadably and detachably receivable by nut 314 .
- platen 187 may be selectively and repeatedly engaged with carrier element 232 during rearward stroke movement of linkage assembly 180 and disengaged from carrier element 232 during forward stroke movement of linkage assembly 180 for facilitating movement of platen 187 from upstream end 82 of hopper 61 to downstream opening 81 of storage body 62 throughout consecutive rearward stoke actuation of linkage assembly 180 .
- platen may be selectively and repeatedly engaged with carrier element 232 during forward stroke movement of linkage assembly 180 and disengaged from carrier element 232 during rearward stroke movement of linkage assembly 180 for facilitating the incremental movement of platen 187 along consecutive forward strokes of linkage assembly 180 from downstream opening 81 of storage body 62 to adjacent upstream end 82 of hopper 61 .
- the controls for controlling the operation of engagement mechanism 282 may be suitably located within cab 59 of vehicle if desired for allowing the operator of vehicle 50 to actuate hydraulic cylinder assembly 290 between the extended and retracted orientations as desired consistent with the preferred operation of hydraulic cylinder assembly 290 as herein specifically discussed.
- the number of rearward stokes and corresponding forward stokes of linkage assembly 180 to move platen alternately between upstream end 82 of hopper 61 to downstream opening 81 of storage body 62 may vary depending upon the length of body 60 .
- apertures 312 of carriage element 232 may be desirably and selectively positioned along the length of carriage element 232 at locations sufficient to cause the desired alignment of pin 294 of engagement mechanism 282 with selected ones of apertures 312 throughout the alternating engagement of engagement mechanism 282 with carrier element 232 throughout forward stroke and rearward stroke movement of linkage assembly 180 .
- joint 258 allows carrier element 232 to pivot and give at joint 258 for inhibiting carrier element 232 from becoming compromised during the compaction operations. Furthermore, because the blanks of the rearward and forward guides 260 and 268 may tend to wear over an extended period of time, the preferred detachably mounting of blanks allows a user to selectively replace the blanks as needed as they become worn as a result of the continued sliding movement of the forward and rearward guides 260 and 268 through channel 241 . Furthermore, and as evidenced in FIG.
- platen 187 may be provided with a pair of opposed guide rails 315 and 316 (also shown in FIG. 36 in vertical cross section) coupled with framework 220 and extending rearwardly from housing 280 of platen 187 in spaced apart, substantially coextensive and substantially parallel relation.
- guide rails 315 and 316 are sized for receipt against either lateral side of each respective I-beam 233 and 234 operative for guiding platen 187 along carrier element 232 , although this is not an essential feature.
